One thing that caught my eye, and this is something I've suspected for some time now: In the U.S. 88% of smartphone users use their phones for entertainment (internet, games, music) while only 83% used their phones for communication (e-mail or social network--doesn't mention phone calls). I'm not clear why they didn't mention the percent that made calls with their phones. I know it sounds silly to talk about how many people use their phones to make phone calls. But I see fewer and fewer people using them for this purpose!
